SMD4042-150E 150V Gas Discharge Tube – SMD4042 Package | RUILON
RUILON
The SMD4042-150E Gas Discharge Tube (GDT) from RUILON is a compact and reliable ceramic surge protection device designed to protect sensitive electronic circuits from transient overvoltage events. Built with advanced gas discharge technology, it provides fast and efficient response to lightning strikes, switching surges, and electrostatic discharge (ESD), ensuring stable and long-lasting protection.
With a DC spark-over voltage of 150V, this device is ideal for low to medium voltage applications where precise and controlled protection is required. Compared to higher-voltage GDT variants, it offers earlier triggering, making it suitable for protecting sensitive components without compromising system performance. It supports high impulse discharge current (8/20µs) and demonstrates strong impulse spark-over performance (1kV/µs) for reliable operation in demanding conditions.
The device features low capacitance at 1 MHz, ensuring minimal signal distortion in high-speed communication lines, along with high insulation resistance to reduce leakage current. Its stable glow voltage and arc voltage characteristics contribute to consistent performance and extended service life.
Encased in a compact SMD4042 package, the SMD4042-150E enables easy surface-mount assembly and flexible PCB design. It is widely used in telecommunications equipment, power supplies, industrial control systems, smart meters, and consumer electronics, delivering dependable surge protection and improved system reliability.
